The defendant, Wayne Racine, was convicted after a bench trial of the crimes of battery of a person sixty-five years old or older and battery. His attorney apparently filed a written motion waiving a jury trial, and the trial court entered an order granting that motion. Racine complains, and properly so, that he did not waive his right to a jury trial and seeks reversal of his convictions and a new trial.

The Florida Constitution guarantees to each citizen that the “[t]he right of trial by jury shall be secure to all and remain inviolate.” Art. I, § 22, Fla. Const.; see also Art. I, § 16, Fla. Const. (providing that the accused shall “have a speedy and public trial by impartial jury”). “[A] defendant’s right to a jury trial is indisputably one of the most basic rights guaranteed by our constitution.... ” State v. Griffith, 561 So.2d 528, 530 (Fla. 1990). 1 This guarantee is also contained in the United States Constitution. 2

The error committed by the trial court is that it conducted a bench trial without obtaining a proper waiver from Racine of his right to trial by jury. For a waiver of the right to jury trial to be valid, a waiver form must be signed by the defendant or the defendant must orally waive that right after a proper colloquy with the trial court. Johnson v. State, 994 So.2d 960 (Fla. 2008); Smith v. State, 9 So.3d 702, 704 (Fla. 2d DCA 2009) (“A valid waiver of a criminal defendant’s right to a jury trial requires either a written waiver signed by the defendant or the defendant’s oral waiver after a proper colloquy with the trial judge.”).

The record before us contains neither a written waiver form nor a transcript showing that Racine orally waived his right to a jury trial before the trial court. The motion signed by Racine’s attorney does not constitute a proper and valid waiver by *957 Racine. See State v. Upton, 658 So.2d 86 (Fla. 1995). We note, parenthetically, that the State concedes the error. Accordingly, we reverse Racine’s convictions and sentences.

REVERSED and REMANDED.
